What else can I help you with?
The anterior root and the posterior root fuse to form?
Each spinal nerve attaches to spinal cord by a ventral (anterior) root and a dorsal (posterior) root.All spinal nerves are mixed nerves (both motor and sensory).
Structures form by the fusion on the anterior root and posterior nerve root?
Spinal nerve.....
What nerve supplies the serratus anterior muscle?
The serratus anterior muscle is primarily innervated by the long thoracic nerve (C5-C7) which arises from the brachial plexus. This nerve provides motor innervation to the serratus anterior muscle, which is important for stabilizing and protracting the scapula during shoulder movements.
What vertebral level does the sympathetic nerve leave the spinal cord?
Fourth thoracic
What area of the spinal cord that is destroyed bye polio virus?
destruction of the anterior horn (Motor Nerve) of the spinal cord. The nerve cells can not regenerate.
What would happen if the anterior ramus of the spinal nerve is damaged or transected?
The end organ or muscle innervated by that particular spinal nerve component would atrophy.
What would be the result of damage to ventral root of a spinal nerve?
Would lead to loss of both sensory & motor function. Ventral ramus is the anterior division of a spinal nerve.
What causes thoracic radiculopathy?
Thoracic radiculopathy is typically caused by compression or irritation of the spinal nerves in the thoracic region of the spine. This can be due to conditions such as herniated discs, degenerative disc disease, spinal stenosis, or trauma to the spine. These issues can put pressure on the spinal nerves, leading to symptoms like pain, numbness, and weakness in the chest, abdomen, or back.
How many nerve pairs are generated from each section of the spinal cord and how are they named?
Humans has 31 pairs of spinal nerve. Here is the spinal nerve pair list: twelve thoracic, eight cervical, five sacral, five lumbar, and one coccygeal.
The neurons of the anterior horn of the spinal cord provide nerve impulses for what actions?
No options given to answer
Motor impulses leave what horn of the spinal cord?
Motor nerve leaves anterior horn.
What are the 31 pairs of spinal nerve?
The 31 pairs of spinal nerves are: 8 cervical 12 thoracic 5 lumbar 5 sacral 1 coccygeal. They are formed by the ventral and dorsal root of the nerve that comes out of the spinal cord.
